The canon of British First World War poetry seems well established and beyond dispute with a set of key ‘representative’ poets referenced continuously. Yet these poets have been selected and promoted over the decades for various reasons. Moreover, how representative were they of the British experience and reaction to the events 1914–1918? Using a quantitative study of the poets and poems appearing in anthologies during and after the war, this essay reconsiders the true canon of the British poetical response to the war charting the rise (and fall) of certain poets and why this might be so. It also considers the hidden canon of poetry that focuses on other theatres of war, at sea and in the air.
